APPENDIX. 



I. 



As the present paper was passing through the press I received 

 an important set of western Aleocharini from Mr. Wickham, of 

 which the two following species deserve notice at the present time. 



]*IYR]»IO BIOTA n. gen. 



Head well inserted, subparallel at the sides, not constricted, the 

 eyes rather small, at distinctly more than their own length from 

 the base ; infralateral carina strong, entire. Antennae thick, the 

 basal joint but slightly longer and thicker than the second, each 

 one-half longer than wide ; third slightly shorter than the second, 

 only very feebly obconical, a little longer than wide; fourth slightly 

 wider than long ; four to ten evenly and gradually but rapidly in- 

 creasing in width, obconical and perfoliate, the tenth nearly twice as 

 wide as long ; eleventh short, conoidal, a little longer than wide, 

 not as long as the two preceding. Maxillary palpi slender ; third 

 joint longer than the second, almost cylindrical; fourth feebly ob- 

 lique, rather small, Mentum transverse, trapezoidal, with a thin 

 translucent apical extension. Ligula with a short thick parallel 

 process which is broadly rounded at apex ; labial palpi three- 

 jointed, the joints distinct, rapidly decreasing in thickness. Pro- 

 thorax narrowed at base, the hypomera broad, entire and hori- 

 zontal. Elytra ample. Abdomen rapidly narrowed from base to 

 apex, the first two tergites broadly impressed at base ; third a 

 little longer than the fourth and much shorter than the fifth. 

 Anterior coxae large and elongate, the intermediate narrowly sepa- 

 rated, the mesosternal process long, gradually finely acuminate, ex- 

 tending nearly to their summits, with its apex free and superposed 

 upon the apex of the short triangular metasternal process. Meta- 

 sternum moderate, the side-pieces gradually wider behind, the epi- 

 mera obliquely truncate posteriorly, the obliquely pointed apex 

 extending behind the elytra. Legs slender, moderate in length*
